Exporting a LUT for use with FFMPEG

Software Natron
1

Hey All,

New to Natron. I Have made a color correct using the color Lookup node. I would like to export this as a cc, cube or other FFMPEG friendly LUT format for scripting and batching. I have attempted to export a CC/CCC via the OCIOCDLTransform node. However, attempting to bring it back in to via the OCIOFileTransfom node, the exported LUT does not inherit the changes from the ColorLookup node above it.

Any insight on how to do this would be amazing!

Thanks!

Use haldclut, or any lut format that uses a standard png image to store the lut

Input a identity haldclut to your color correction process, and on output you get the baked haldclut.
Save it, and you can then apply it using ffmpeg:
